1939 Totals

771 made vs 421 used
note: leaving the obsolete planes on the airfields and not using them in combat was, perhaps, one of the bigger errors that the Polish High Command committed; in spite of that the crews would have most likely died (the crews could have been chosen from the terminally ill—the Poles almost certainly knew about the Nazi policy of killing all terminally and mentally ill, since Poland had been asking other countries, based on her own intelligence, for a pre-emptive war against Germany between 1934 and 1937), they could have kept the German airforce busy
note: not using the air planes in great numbers before the 3rd of September was perhaps another error
